4 INTRODUCTION Achieving the best results takes time and dedi-cation. It all boils down to carefully selecting the right material to work with during every step in the production process and in every single component. Having Uddeholm as a partner will enable you to find new costeffective solutions. We are happy to be your partner throughout the whole process from the initial ideas through to the finished product. Uddeholm is a world-leader in developing and manufacturing tool steel. Using our tool steel in finished components, a concept we choose to call Uddeholm Component Business, produces better results and a longer life span. IMPROVED PROFITABILITY WITH UDDEHOLM TOOL STEEL Uddeholm Component Business offers a solution where the first class tool steel of Uddeholm comes to use in components and applications where conventional engineering and stainless steel provide an insufficient solution. The qualities of tool steel contribute to an optimized design, increased performance, lower maintenance costs and the best overall economy. A high proportion of these costs can be avoided when selecting a steel grade with better material properties. BUSINESS ECONOMY FOR BRAN FLAKES PRODUCTION Using Uddeholm Caldie in rolls for Bran flakes production gives lower production and maintenance costs. A customer used A2 material in the rolls. This resulted in 500 production hours and eight production stops per year. By instead selecting Uddeholm Caldie, the production time increased to 1800 hours and only two stops per year. Selecting Uddeholm tool steel gives the best production economy. 4 APPLICATION COMPONENT BUSINESS

5 Uddeholm Component Business applications and components can be found within any industry where there are high demands on properties such as wear resistance, strength, corrosion and heat resistance. LESS DOWNTIME AND HIGHER STRENGTH When it comes to comparing the strength of different steel grades it is soon evident that Uddeholm s tool steel show far better strength values compared to engineering steel grades. The advantage here is that the adaptive hardness of the material through quenching and tempering can be exploited according to specific demands. High fatigue strength can be achieved when combining the high strength and cleanliness of the steel. Uddeholm s ESR grades are good example of this. This means a longer life for the finished component and these properties also enable weight reductions, which lead to lower costs and higher performance. Teams, in for example rally cross and circuit racing, have for many years been using drive shafts from different retailers who have chosen Uddeholm Orvar Supreme as material for their superior products.

6 HIGHER WEAR RESISTANCE LONGER LIFE SPAN Wear costs industrial companies a lot of money every year largely due to abrasion. Within this area the key is to optimize strength and abrasion resistance. Uddeholm s product range includes steel grades with a high level of combined durability and toughness. Certain grades for cold work tools are especially well suited to withstand wear due to their structure containing hard phase particles. STEEL WHEEL USING UDDEHOLM IMPAX SUPREME Normally wheels, which go with low speed and high load, are manufactured in cast iron. When changing materials in the wheels of a load car from cast iron to Uddeholm Impax Supreme, with a nitrided surface, a cost reduction of approximately 60% was achieved due to a radically increased life span of the wheels. Uddeholm Impax Supreme was supplied at 310 HB and the nitrided surface layer had a thickness of 0.4 mm and a hardness of 750 Hv.

7 WITHSTANDING WEAR AT HIGH TEMPERATURES Uddeholm s steel grades are also used in hot forging tools and consequently developed to withstand high temperatures. This property means major improvements in strength for parts that are exposed to heat during a long period of time, i.e. they are not losing strength and hardness as often in the case for engineering steel due to tempering back. KNIFE FOR CUTTING OF HOT STEEL BILLETS WITH UDDEHOLM UNIMAX Uddeholm Unimax is perfectly suited for the cutting of hot steel billets. The billets cut in this case are approximately 1000 C (1830 F) and made of the steel grade C45. The knife cuts at a speed of 120 cuts/ hour. Originally, the knives were manufactured in W.-Nr with a hardness of HRC. These knives could perform cuts before they needed to be changed. The knives wore out due to chipping and cracking. The solution was knives in Uddeholm Unimax at 56 HRC. The life time was extended to cuts. No more problems with cracking have appeared after this change. Knives in Uddeholm Unimax for billet cutting.

8 CORROSIVE ENVIRON- MENTS DEMAND HIGH QUALITY Uddeholm s range of corrosion resistant steel, often used for plastic moulds, provides a unique combination of strength, corrosion resistance and durability, which enable brand new technical design solutions. This means that components do not need to be surface treated and the material can be used in environments where corrosion would normally be an issue. CAR BATTERY FRAGMENTATION USING UDDEHOLM STAVAX ESR A car battery recycling company had poor lifetime of their knives. The reason for that was that the acid in the batteries together with caustic soda caused heavy corrosion, which resulted in cracks and total breakage of the knives. A change of steel grade from X155CrVMo 12-1 (D2) to Uddeholm Stavax ESR resulted in a dramatically increased lifetime, from 2 days to 6 weeks. Before the change in materials the customer was afraid that the knives would break and cause accidents. Now he feels safe with the knives, can reach higher profits and experience, much lower maintenance costs and downtime. Car battery recycling knives.

9 FEEDING AGERS FOR MEAT GRINDING IN UDDEHOLM CORRAX The machine is designed for grinding of both fresh and frozen meat down to -20 C. Many components in the machine are made of stainless steel. One of the feeding agers is made of Uddeholm Corrax, which is part of the Uddeholm Stainless Concept. Feeding ager in Uddeholm Corrax for meat grinding. Uddeholm Corrax provides a number of advantages: high strength of a stainless steel optimal combination of corrosion resistance and wear resistance high ductility and toughness welding benefits, the coil is welded to the core (axis) and both elements are made of Uddeholm Corrax less downtime less maintenance costs a multiplied life span of the component UDDEHOLM STEEL GRADES CERTIFIED BY NORMPACK For the requirements in the food industry some of Uddeholm tool steel grades are certified according to the European Union legislation (1935/2004). The Normpack norm includes and fulfills the European Union framework legislation regarding materials that come into contact with food.
